The Fock exchange term has been implemented in ABINIT, both in the norm-
conserving pseudopotential framework and in the PAW one. Some details about
the implementation in ABINIT can be found here.
For an ABINIT user, to make a calculation of Fock exchange:
- do a first GGA dataset for the ground state
- do a second dataset for the Fock calculation choosing ixc=40-42 (HF,
PBE0, PBE0-⅓), -402 (B3LYP-Libxc), -406 (PBE0-Libxc), -456 (PBE0-⅓ Libxc),
or -427, -428 (HSE03, HSE06).

The energy, forces and stresses are available in the norm-conserving and PAW
frameworks.
A one-shot G0W0 calculation can follow, only in the norm-conserving case at present.
